Lets say you have two bunnies. One has a long tail, the other has short tail. The one with the long tail died because a predator was able to catch onto the long tail and eat it. Therefore, the long tailed bunny can't pass on the characteristic of a long tail and that trait is no longer seen in bunnies. However, the bunny with the short tail isn't caught by predators as easily, and as a result, passes on the trait of a short tail to its offspring. After a long amount of time, no bunnies will have long tails because all the bunnies with long tails were killed out, and as a result, can't pass on the characteristic of a long tail. Bunnies then evolve to always have short tails.
When a species contains few mutations
Natural selection has been, is, and will always be an ongoing process. A member of a species is born with a major or minor modification.
Natural selection would occur in evolution. Only those with the best traits will be able to continue on the species.
a population of salmon with different skin colors that attract mates
When there are to many of the same species, the animals with the better adaptations survive.
No scenarios, but......
What results from natural selection in the long run is adaptive change and this can, under the right environmental conditions, lead to speciation.
Which example best illustrates a condition necessary for natural selection to occur?
when there is competition
To begin with, a theory can not prove or disprove anything until it is proven itself.
natural selection occurs when animals need it
Natural selection is the means by which living things are selected to reproduce. It is called natural because it is what happens in what is considered ordinary living conditions. It works by allowing only those creature capable of surviving getting to reproduce. If a creature is incapable of living/surviving in the environment that it finds itself in then it doesn't reproduce and becomes extinct.
Adaptation does not allow for natural selection: natural selection causes adaptation.
No, natural selection is the mechanism that drivesevolution.
natural selection occurs due to natural phenomena (e.g. changes in diet or predators).artificial selection occurs due to human generated phenomena (e.g. breeding or domestication).
natural selection
Yes, of course it does.
natural selection
no
no, at the individual level
It is an example of Natural Selection, Modern Theories of Evolution.
Disruptive selection, also known as diversifying selection.
